Question

Calculate the mass of water molecule obtained by burning 16g Methane.​

Answer 1

Answer:

Explanation:

Combustion of methane :

CH4​+2O2​⟶CO2​+2H2​O

Given weight of methane =16g

Molecular weight of methane =16g

No. of moles of methane in 16g of it =mol. wt.given wt.​=1616​=1 mole

From the reaction,

Amount of water produced by the combustion of 1 mole of methane = 2 moles

weight of 1 mole of water =18g

⇒ weight of 2 moles of water =2×18=36g

Since, the given weight of methane is 16 g, hence the water produced by the combustion of 16 g of methane is 36 g
